5 Series E34 525td (M51) TOUR
Necessary preliminary tasks:
Before actually testing for leaks, check the entire refrigerant circuit
using the UV leak-detecting lamp to ensure that no AV additive is
already in the area of the refrigerant circuit.
If already illuminated areas are found, carefully clean the area in
question with the cleaning agent contained in the case.
On initial use:
Connect hand pump (1) to additive cartridge (2) and hose
piece (3).
On initial use:
Attach vent valve (1) to quick-connect coupling (2).
Turn handle (3) on hand pump to advance the plunger until a
small amount of UV additive emerges. This vents the hose
system.
Important!
The entire hand pump with hose system must not be
disassembled again once the filling work has been completed.
Attach quick-connect coupling (1) to low-pressure
connection (2) of A/C system.
Turn handle on hand pump (3) until the required amount of UV
additive is added.
The quantity of UV additive to be added is dependent on the
amount of refrigerant in the refrigerant circuit:
•
A/C systems with refrigerant filling up to 900 g:
one graduation mark (4) on additive cartridge
•
A/C systems with refrigerant filling in excess of 900 g:
two graduation marks (4) on additive cartridge
